It appears that Walt Disney Imagineering has begun the test and adjust phase for the brand new Dumbo attraction being installed in the Storybook Circus area of the New Fantasyland Expansion at Magic Kingdom in Walt Disney World. Photos and video captured by MouseSteps demonstrate some of the vehicles in action yesterday.

What makes this particular installation of the classic attraction is that this will be the first time in any Disney theme park that Dumbo will fly in a clockwise direction (i.e., if you were to look at the attraction from an aerial vantage point), or more simply put, Dumbo faces left. In every other installation, Dumbo flies in the opposite (counter-clockwise) direction. The attraction topper is also more ornate than previous incarnations, replacing Timothy Mouse with a bevy of storks mid-job.

The existing Dumbo attraction is expected to close on January 9 and be relocated to its new space, next to the new Dumbo attraction, offering guests a ‘Dueling Dumbo’ effect when the attraction is expected to re-open on February 18, 2012 for Presidents’ Day Weekend March 12, 2012.

Effectively doubling the theoretical hourly ride capacity (THRC), Dumbo is also expected to offer another Disney first: no traditional queue. Instead of guests lining up for what is notoriously one of the longest and slowest queues in the parks, a circus tent area will offer entertainment for guests as they wait for their respective boarding group to be announced, as was previously tested at Rock’n’Roller Coaster at Disney’s Hollywood Studios.
